Building my fuselage in Phx. Az. Really hot, dripped sweat, "one drop" on skin. Tried to wipe off with rag. Didn't come off. I think it etched into the aluminum. I wiped off with lacquer thinner and it took it down to a dark metal finish. Will coating it with zinc-chromate primer keep the spot from getting worse?
